LIGHT-SUPPOBT. A

Specification 0f Letters Patent Patented Sept. 24, 1.918.

Application filed-September 29, 1917.- 'Serial No. 194,013.

To all 'whom it may-concern.' .A

Be 't known that I, GEORGE. F. WATSON, a subject of Great Brita-in74residin at Rockland, in the county of Knox an Maine, have inventedcertain new and useful Improvements in LightSupports, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

T his invention relates to certain improvements in light supports and itis an object of the invention to provide a novel and improved device ofthis general character wherein a Hexible stand is employed and whereinsaidlstand comprises a plurality of relatively movable members.

' The invention also has for an object to provide a novel'and improveddevice of this general character including a plurality of relativelymovable members and wherein said members are maintained in hperativerelation and in various positions `through frictional Contact `andwherein said friction is created by a retractile member disposed throughthe members and secured to the end members.

A still further object of the invention yis to provide novel andimprovedmeans whereby the tension of the spring coactin'g with Athe movablemembers may be regulated upon relative, movement of certain of 4themembers comprised-in the stand.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my imn provedlightsupportwherein certain important advantages are attained and thedevice rendered simpler, less expensive and otherwise more convenientand advantageous i'or use, as Willbbe hereinafter more fully set tort 1The novel features of my invention will hereinafter he definitelyclaimed.

In' order that my invention may be the better understood I will nowproceed to describe the same with'reference to the a'ccompanyingdrawings wherein: v

Figurel is a view in elevation of a light support constructed inaccordance with an embodiment of my invention;

- Fig. 2 is a-sectional view taken substantially on the line 2v2 of Fig.1;

F1 3 is 'a fragmentary longitudinal secs tiona view taken through thebase portion of my improved support;

' Fig. 4 is .a longitudinal sectional view State of taken through oneofthe movable members comprised in the support as herein dis closed; and

F ig. 5 isa fragmentary-view partly in section and partly 'in elevationillustrating the outer member ot' my improved support together with theco-acting portion ofa lamp receiving socket.

As disclosed in the accompanying draw-- ings l denotes a base member ofpredetermined dimensions and configuration and which has resting uponits upper face at substantially itsaX-ial center a circular block 2. Thelower marginal portion oi the block is provided with an annular-.flangef5 through which is disposed the headed screws 4 or the like forsecurely holding the blockl i5 in applied position.

5 denotes an elongated cylindrical sleeve, open at bothends and havingits lower end portion surrounding the block 2. The sleeve 5 is alsocapable of rotary movement about the block 2 for a purpose which willhereinafter more fully appear.

Telescopicallyengaged within the' member V5 is a secondfcylindricalmember 6 eX- .2' isxgradnally reduced on a predetermined taper andterminates in the substantially spherical enlargement or head 8.FrietionnllyI engaging theenlargement or head y8 is the open end portionot a hollow member 9 preferably in the form of a truncated cone andhaving its outer end provided with the substantially sphericalenlargement or head l0. ,Co-acting withthe member 9 and with each otherare a plurality of members ,11, each of. said members beingsubstantially the same construction and formation as the member 9although each of said members l1 outwardly from the member 9, are-.ofgradually decreasedv dimensions.

Fctionally'engaging the head 12 l,of the outermost member l1 is a.tubular member 14 substantially in theV form of a truncated cone andhaving its outer end 15 closed.

The closed end 1.5 at the axial center thereof is provided-with anopeningl defined by,4 an outstanding annular ange 17 with whichisthreaded or otherwise engaged the socket v member 19 co-acts with themembers 14 2 BEST .FNAIM-LELE COPY end 15 of the member 14. Thelower oryop-- posite end portion of the expansible member 19 is suitably anchoredvas at 21 to the block 2 hereinbefore referred' to. The expansible'member 19 as herein disclosed comprises a coil spring and it has 'beenfound best practice to have the convolutions of sald spring formed offlattened material. The

and the block 2 to constantly urge the members 14, 11, 9 and 7 inwardlso that the requisite frictional co-action tween said members is assuredin order tomaintain the stand as afforded bythe members 7, 9, 11 and 14in a vertical position or in any other position to which the stand maybeflexed or bent. v

In order to' regulate the tension of the member 19 in accordance withthe require-l ments of .practice and to properly assure the requisitefrictional contact of the members comprised in my improved stand themember 5 has produced therein the substantially V- .shaped slot 22. Theapex of the slot 22 is disposed transversely of the longitudinal axis ofthe member 5. The member 6 is provided with an outstanding pin or lug 23extending 'within the slot 22 and co-actmg with the lower edges or wallsof said slot. It will be at once perceived that upon rotating the member5 about the block 2 the pin or lug 23 will ride upon a lower ed e of theslot 22 and either raise or lower 51e member 6 resultmg in eitherincreasing or decreasing the tension of the member 19. In order to maintain the sleeve 6 at various positions longitudmally of the member 5 Iprovide the lower walls of the slots 22 with the recesses or notches 24in which the pin or lug 23 is adapted to seat. I

Leadin from the socket S and disposed through t e coil sprin 19 are theconductors a leading from the soc et S. The conductors a are alsodisposed through the registering openings 25 produced in the base member1 and the block 2. 'Ihe conductors a are then continued throu li thegroove or channel I 26 produced in t e under face of the base 55 member1 and' which groove or channel radiates from the opening 25. Theconductors a are adapted to be connected in any desired manner withsuitable electrical source. It is also desirable to provide the bottomface of the brace member 1 with a lamination -27 of felt or other softmaterial for a purpose which is believed tobe self evident.

From the foregoing description, it is thought to be obvious that alightsupport constructed in accordance with my invention is particularly welladapted for use by reason of the conveniencenand facility with which itmay be assembled and operated and it will also be obvious that myinvention is susceptible of some change and modification withoutmaterially departin from the principles and spirit thereof an for thisreason VI do not wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown in carryingout my invention in practice except as hereinafter claimed.

I claim:

A light support comprising a plurality of members having adjacent endsin frictional contact andl movable one relative to the other, a base, atubular member rotatably supported by the base, an end member beingtelescopically engaged within the tubular member, a lamp carried by theopposite end member, a retractile member disposed through each of themembers and secured to the lamp carrying member andto the base formaintainingfthe members in frictional :l contact, said rotatable tubularmemberbeing provided with a substantially V-shaped slot with'its apexdisposed transversely of .the tubular member, and a lug carried'b theportion of the member within the tu ular member and extending said slotwhereby said last named member is moved longitudinally of the tubularmember upon rotation of the tubular member.

In testimony whereof I hereunto aix my. .i

signature in the presence of two witnesses.
